Beloved by construction workers, billboard pasters, and snowplow drivers the world over, Michigan’s Carhartt makes clothes that can take a beating: sandstone jackets, tough twill pants, waterproof work boots. But recently, the 120-year-old brand has begun catering to a more, shall we say, effete audience, with its urbanite-targeting offshoot, Carhartt Work in Progress. The new label has opened 40 stores abroad and launched collaborations with fashion darlings like A.P.C. and Hiroshi Fujiwara of Fragment, plus Vans. And now its greatest departure from blue-collar-dom: a flagship in Soho (119 Crosby St., nr. Prince St.; 212-219-2934), where ample wood paneling surrounds functional separates for men and women as well as collaborative merch like A.P.C.’s fur-lined hunting jacket ($370) and Fragment’s pima-cotton tees ($50).
